Mazut M100 Supply
ALGHAF MARINE FZCO supplies Mazut M100 as a GOST residual for industrial heating and power — not as an ISO 8217 marine bunker grade. RFQs written Mazut, M100, M100-75 or M100-99 are handled against the contracted GOST 10585 table. Non-sanctioned origin is available for selected programmes.
What Is Mazut M100?
Mazut M100 is CIS heavy fuel oil. Unlike HSFO / RMG 380, the GOST table discusses viscosity at 80 °C, not 50 °C, because the product is handled as a heated residual for boilers and furnaces. Pour-point related markings M100-75 and M100-99 appear in RFQs and must be stated if required.
02 Specification
Mazut M100 Specifications
Where GOST 10585 is the contractual reference, the table below is the typical M100 discussion set. Marking (M100-75 or M100-99), sulfur grade and cargo CoA still have to be written into the SPA. Not a standing Alghaf analysis.
Mazut M100 GOST 10585 — typical discussion limits
| Parameter | Typical / discussion limit |
|---|---|
| Standard | GOST 10585 (marking as contracted: M100, M100-75 or M100-99) |
| Viscosity at 80 °C | typically discussed max 16 °E (about 118 mm²/s) for M100 |
| Flash point (open cup) | typically discussed min 110 °C |
| Pour point | typically discussed max +25 °C; M100-75 / M100-99 identify the GOST table / pour-point framework |
| Water | typically discussed max 1.0% mass |
| Sulfur | grade-specific in GOST RFQs (commonly 0.5 / 1.0 / 2.0 / 3.5% discussion bands) |
| Ash | per contracted GOST 10585 table — not treated as a universal Mazut number |
| Mechanical impurities | per contracted GOST table |
Viscosity is quoted at 80 °C on Mazut RFQs. Mapping Mazut onto HSFO 380 CST (viscosity at 50 °C) without converting the table is a specification error.
Mazut M100-75 vs M100-99
Mazut M100-75 and Mazut M100-99 appear as separate tender markings, not as two names for one interchangeable cargo. In GOST 10585 RFQs they identify the applicable standard table and the pour-point / quality framework the buyer expects. Sulfur, viscosity and other limits still have to be written into the SPA; the marking alone is not a full specification.
If the enquiry names M100-75 or M100-99, that marking is carried into the commercial documents. If only “Mazut M100” is stated, the required GOST marking is confirmed before an indication is issued.
Mazut M100 vs HSFO
HSFO is marine high-sulfur residual language. Mazut M100 is GOST residual language. Mapping one RFQ onto the other is only valid if sulfur, viscosity and the standard are agreed. See HSFO supplier.
03 Origin
Non-Sanctioned Origin Mazut M100
Non-sanctioned origin Mazut M100 is available subject to destination and compliance review. Origin is confirmed commercially. Execution hub is not origin.
04 Delivery
Mazut M100 FOB & CIF Supply
Mazut M100 FOB Supply
Mazut FOB may be evaluated from the heated-residual loading point of the cargo programme. Pour-point marking (M100-75 or M100-99) and heating requirement have to be named — GOST 10585 is not a marine bunker nomination.
Mazut M100 CIF Supply
Mazut CIF may be evaluated to approved industrial / power destinations. Heated cargo logistics, if required, are confirmed in the indication. This is not an ISO 8217 bunker CIF.
Mazut M100 Supply Hubs
UAE, ARA / Rotterdam, Mediterranean, Southeast Asia, Black Sea and other approved locations may be used for transaction-specific execution.
05 Price & enquiry
Mazut M100 Price
Current pricing depends on specification, quantity, origin, supply hub, Incoterm, destination and shipment window. Related residual market context may be taken from HSFO 380 CST history where relevant to the RFQ — it is not a Mazut M100 quote.
How to Buy / Request Mazut M100
- GOST marking: M100, M100-75 or M100-99 if used
- Specification, quantity, FOB or CIF, destination, window
Mazut M100 frequently asked questions
What is Mazut M100?
Mazut M100 is a residual fuel-oil designation widely used in CIS and international RFQs, commonly referenced to GOST 10585. M100-75 and M100-99 are pour-point related markings used in that framework. The contracted GOST table and CoA define the cargo, not the search term alone.
What is the current price of Mazut M100?
Mazut M100 price is transaction-specific. It depends on GOST marking, specification, quantity, origin, hub, Incoterm, destination and shipment window. No standing dollar-per-MT figure is published here.
What are the typical specifications of Mazut M100?
Where GOST 10585 is contracted, typical M100 discussion covers viscosity at 80 °C (often max 16 °E / about 118 mm²/s), flash point open cup min about 110 °C, pour point often max +25 °C, water typically max 1.0%, and sulfur as a named GOST grade band. M100-75 / M100-99 identify the GOST table / pour-point framework. Ash follows the contracted table. SPA and CoA govern.
What is the difference between Mazut M100-75 and M100-99?
M100-75 and M100-99 are distinct Mazut M100 discussion markings used in GOST 10585 RFQs. They are not interchangeable nicknames for the same cargo. Buyers use them to identify the applicable GOST table and pour-point / quality framework required for the lot. The contracted marking is confirmed in the SPA; CoA values are cargo-specific.
Is non-sanctioned origin Mazut M100 available?
Yes. Non-sanctioned origin Mazut M100 is available for selected cargo programs, subject to specification, allocation, destination and compliance review. Origin is confirmed commercially and is not implied by the execution hub.
Do you supply Mazut M100 FOB?
Yes. Mazut FOB may be evaluated from the heated-residual loading point of the cargo programme. Pour-point marking (M100-75 or M100-99) and heating requirement have to be named. GOST 10585 is not a marine bunker nomination.
Do you supply Mazut M100 CIF?
Yes. Mazut CIF may be evaluated to approved industrial / power destinations. Heated cargo logistics, if required, are confirmed in the indication. This is not an ISO 8217 bunker CIF.
Which supply hubs are available for Mazut M100?
Transaction-specific execution may be arranged through UAE, ARA / Rotterdam, Mediterranean, Southeast Asia, Black Sea and other approved locations. This is not a claim of standing tanks at those hubs.
What is the difference between Mazut M100 and HSFO?
Mazut M100 is a GOST residual designation. HSFO is a marine high-sulfur residual category. Physical streams can overlap, but a Mazut M100 RFQ is not automatically an ISO 8217 RMG 380 stem. Grade, sulfur and viscosity must be stated in the SPA.
How can I request a commercial offer for Mazut M100?
Provide GOST marking (M100, M100-75 or M100-99 if used), specification, quantity, destination, FOB or CIF, window and company details. Following qualification, ALGHAF MARINE FZCO can issue a commercial indication.
